2012 Prius c cv axle seated all the way ?

That tone ring needs to be in alignment with the sensor You should have codes if it's not worth for some reason it's seeing is everything is okay that's pretty strange

 

You'll be able to tell is the CV axle is the wrong part when you get the new one you ordered and compare the two. Same with the control arm.
The thing you mentioned a few posts ago about the angle of the ball joint (and the picture of it ) combined with the statement that you had seated the outer CV shaft into the hub all the way, but it slipped out again (( man that was a kicker )) I'd never heard of that happening, much less experienced it myself.

When I mentioned in my first post to your thread here, that if the CV spline slips out, even a little, the car wouldn't move, I was referring to the inner CV axles spline where it goes into the transmission. I hadn't firgured out at that point this was all about the Hub / outer CV connection.

I'm glad @Tombukt2 was able to explain things that give you more confidence in replacing the axle and control arm. I've done a few of those replacements ( CVs / axles ) on non toyota cars, and they are nice when everything fits together properly, not so nice ( when they don't fit right ) or slip out. Yeah, I've been there.

Don't forget to check / replace that ball, if you are pretty sure it has play.

 

Probably not enough worth discussing does Pop the one out after you have all the front end of it pretty much ready to pull right out and pop that transmission end out pull on the hub and strut and the spline pulls out and sling the axle out sling the other one up in there and put the transmission end in first You've got to make sure you clock that little lock ring the right way generally it right at 6:00 so when it goes in the circle can just gently close and snap in place

 

I've read the same thing recently about the C clip at the end of the spline that goes into the trans. The opening in that clip usually is know to slip into the slightly beveled transmission hole when that opening in the clip is closest to the ground at 6 o'clock on the dial.
Hope ya get that extreme toe in back into line, whatever it turns out to be that made it so far out.

 

Someone replaced it before, it's second hand car?

 

This is one of the many reasons; why I don't buy salvage title cars.
IMHO: If the car was performing satisfactory over the last two years; stick with the Prius parts not the OEM Prius C parts. Whomever put together that front end already 'reinvented the wheel' with regular Prius parts, trying to mix and match whatever suppose to go in there is simply asking for trouble.

Good Luck.

 

It shouldn't make any difference if there's enough of an adjustment to take up that extra length and there must be because you're alignment has been on I guess because the car's been driving okay unless you're wearing out tires really funny in the front end generally those tie rods thread into tubes and usually you can go all the way down so there should be enough adjustment to get the toe and the green on the alignment machine if this is not the case your alignment guy would be telling you very quickly The drive axle probably would be similar as long as it's somewhat seated the snap ring is in where it's supposed to be because it's sticking out just a little is not enough for it to be considered unseated You don't like the way it looks okay but it's in service and working fine it's not shaking rattling doing anything that it shouldn't be doing so it's seated and working It's just not exactly like the factory one made for the car it would be up against that cup and look correct but if it's working fine and you can manage leave it alone if you can't then get your gun out and your jack stand and a jack and change it that too shouldn't throw your alignment off but you're alignment guy would tell you very quickly as that would push things out or try to bring them in but I highly doubt the drive axle would be causing any of that The tie rods absolutely could but if you got an alignment or they did after they were done and the guy could get it in spec that would be no mention

 

So where do you stand on alignment I mean that's the first thing I would think you'd want to know this all started with a drive axle not being seated up against the dust shield or whatever If I remember correctly now we're off to wandering suspension components The Prius c is more like a generation two It's a tad smaller and so on suspension layout very similar but the parts may be shorter that sort of thing but if it's enough that the threads can take up the slack and make it all happen and your alignment isn't correct then in that area it would make no difference other than you would know the parts are wrong and every time something went wrong you're going to blame those parts but that's not how this works or supposed to work. So maybe you need to get an alignment shop involved see where you stand how much you're in the red on all your settings in other words that sort of thing how fast the alignment guy comes running back into the waiting room and goes whoa or what have you then you've got a place to start but if you're alignment is good and everything is reasonable there maybe you have a tire problem slipped belt so on.
